Sweetened condensed milk is one of those things that you don’t need until you need, at least in my kitchen! I usually had a can lurking in the back of my pantry. It moved from apartment to apartment…until I needed it one day when I decided to test out making my own homemade coffee creamer, and I realized it was way past acceptably expired.

I quickly learned that making your own isn’t only easy, it’s better. Sweet, syrupy thickened milk all warm and delicious…it’s seriously scrumptious enough lick from your spoon…and pot. (No judgement here!). Bonus is, even using organic milk, it winds up being as inexpensive, if not cheaper than the store bought stuff. This is especially true if you’re in the market for dairy free sweetened condensed milk. Plus, you can make it when you need, freeze the extra, and cut out that last minute store run!

The Ingredients

Thankfully, homemade sweetened condensed milk is remarkably simple. Milk and sugar is all you really need. In an easy, 3 to 1 ratio of milk to sugar, I thought I’d share some tips on choosing the milk and sugar that work for you.

Milk – Choosing milk is important! Your choice will absolutely affect the thickness, richness, and flavor of the final product. A few tips…

  • A full fat milk will yield a creamier, thicker product. Whole cow’s milk is my preference, but you can even use heavy cream if you’re after a seriously luscious final product.
  • You can use ANY non-dairy milk you want! Almond milk will yield a thinner, runnier condensed milk while coconut will be very thick.
  • Depending on your milk choice and you’re intended use, you may need to reduce it less or more than my recipe to get the right thickness.

Sugar – for the most similar flavor to the canned condensed milk, white granulated sugar is my preference. However, you again have choices! A few tips, and warnings, to get you going on the right foot.

  • The sugar you use has a strangely minute effect on final flavor. Using the most expensive cane sugar I could find didn’t produce a better homemade condensed milk than generic granulated sugar.
  • You can use: Granulated, cane, turbanido, coconut sugar, or even pure maple syrup (so expensive though!).
  • Brown sugar contains molasses and due to the acidity content of molasses, this can cause curdling in your condensed milk. I personally have not had any issues with turbanido sugar, but brown sugar has on occasion caused this. Since it makes NO difference in flavor, I don’t recommend doing this.
  • Stevia or Splenda, or any other sugar alternatives do NOT work the same as sugar. I recommend using only sugar substitutes that can be exchanged in baking as a 1 to 1 replacement.

Other Ingredients – When I first began testing, many recipes called for butter, baking soda, or vanilla. I found each of them completely unnecessary.

  • While butter may lend richness, it also separated in the jar after cooking. Condensed milk is plenty rich on it’s own.
  • Vanilla may add flavor, but it really, really isn’t needed. Instead, wait to add flavoring until you’re using your sweetened condensed milk in your recipe.
  • Baking soda, as food scientist reader kindly pointed out, can aid in the caramelizing of the sugars. This is only really desired if you’re cooking past the point of sweetened condensed milk into dulce de leche. If that’s the case, go ahead and add a half teaspoon or so.

My advice – keep it simple and inexpensive, just use milk and sugar.

How to Make Sweetened Condensed Milk

Making homemade condensed milk is a very simple process! What’s important is the ratio and the time. 3 cups (24 ounces) of milk and 1 cup of sugar is the perfect ratio for ideal sweetness and thickening. With whole milk, this yields about 1 cup of condensed milk.

For those using skim, almond, or other thinner milks, to achieve a thicker end result you’ll have to reduce longer and therefore it will yield less.

Pro Tip: Using your condensed milk for drinks like Thai iced tea or homemade coffee creamer? Reduce your milk less for a thinner, more beverage friendly end result.

Making homemade sweetened condensed milk is as simple as the ratio. Mix milk and sugar, reduce. That’s it. The name really does say it all, you’re simply condensing milk with a sweetener.

Fast Method – adding sugar to milk changes the nature of it, reducing the risk of scorching your milk. This makes it possible to cook your condensed milk in under an hour. Be advised, the scorching risk is reduced, not eliminated.

  1. Combine your milk and sugar in a pot and place it over medium high heat.
  2. Stir as it heats to dissolve the sugar.
  3. Continue to stir until the mixture comes to a gentle boil, then babysit.
  4. Stir frequently. Scrape along the bottom to prevent scorching, until your milk is reduced by 2/3 and thickened.

Slow Method – This method lets time and gentle evaporation do the job while you’re free to wander away and work on other things! (If you’re curious, remove the sugar and you can make evaporated milk this way too!)

  1. Combine milk and sugar in a pot and place is over medium high heat.
  2. Stir as it heats to dissolve the sugar.
  3. Continue to stir until it comes to a gentle boil, then crank it down to low. Continue to stir until the mixture is steaming rapidly, but not bubbling.
  4. Give it a stir every 20 minutes or so, until your mixture has reduced by 2/3, around 3 hours.

When your done, regardless of the method you choose. Pour your condensed milk into a storage jar and allow to cool. It will thicken as it cools. Seal and store in the fridge for up to 1 month, or in the freezer for up to 3.

Bonus tip – to check how much the milk has reduced, you just need a wooden skewer and a marker. When you first put the pot on, mark the milk level with the marker. When the milk level is one third the height of the original, you’re all done.

It’s not as thick as I wanted it, even after cooling, can I fix it?

Yes, if you’re not happy with the thickness you can reduce it further by returning it to a pot and cooking it more.

Is it possible to can condensed milk for shelf storage?

The only way I know of to make homemade condensed milk safe for shelf storage is to use a pressure canner. If you have one, refer to your pressure canners instructions to do this safely.

Can I make it with evaporated milk?

Yes, If you have a can of evaporated milk, you can dissolve sugar into it over gentle heat to create a similar product.

Can I make it with powdered milk?

Yes, it can be made with powdered milk if you have more of that available to you than powdered milk. Here’s a link to a great blog post on how to make it with powdered milk!

My condensed milk cooked too long and started to look like caramel, is it bad?

NO! While it may not have been your intention, the stage beyond condensed milk is dulce de leche. Delicious, caramel and definitely not ruined. Whether you’ve cooked it all the way down to real dulce de leche or you have just a hint of caramel flavor, it’s fine to use.

  • 1 Cup Sugar Use sugar of choice: granulated, cane, turbanido etc.
  • 3 Cups Milk Any milk of choice!


  • Combine sugar and milk in a large pot over medium heat.
  • Bring to a boil, stirring to prevent burning. 
  • Once boiling, reduce heat to low, maintaining enough heat to keep milk steaming.*
  • Stir every 20 to 30 minutes until milk has reduced by two thirds, or is close to desired thickness. (It will thicken as it cools)
  • Pour into storage jar and allow to cool. Seal tightly and store in fridge up to 1 month. 


Measure how much your milk has reduced by marking initial levels on a wooden skewer or chopstick and comparing over the course of a few hours.
*I’ve had success with brown sugar, but due to the molasses content in brown sugar, it can cause curdled milk. I recommend using turbanido sugar if you’d like to use brown sugar, or sticking to white sugar. (It really doesn’t affect flavor)
*If you prefer a quicker reduction, keep the heat at medium high and stir almost constantly until reduced to desired point. There is an increased risk of scorching, so don’t leave it.

    Addendum- my milk separated at the end of cooking. I used a blender stick and it all blended together to a smooth, silky texture. Mine was also a bit darker, so I may have overcooked or temp got too high during reduction, but it was an easy fix. It’s quite delicious. Thanks for this recipe!

    1. Hi there Vicki, I’m glad you were able to fix your milk, I’ve had the curdling happen when I get impatient with heat yes, but also if I used brown sugar or something similar to that. If your condensed milk is darker, sounds like heat was the factor, and it’s totally fine! You were just on your way to making dulce de leche! Thanks for sharing your experience!

  2. I made this however during the last 30 minutes of cooking the milk separated. . It tastes fine but looks curdled. Any idea why this happened? I wonder if the heat may have been too high?

    Have you had any issue making this in bulk? I want to use in a holiday recipes and I need a higher quantity and want to possibly quadruple the recipe. Thanks!

    1. Hi, I make it in bulk frequently! I usually do a gallon of milk, which is 5 times the recipe, plus some. It does take some time, so be prepared to wait a little, but it works just fine. Have fun with your holiday baking!

    1. Hi Linda, I think using the slow cooker sounds like a great idea! I would definitely keep it on low, and leave the lid off so the milk can evaporate properly. Still stir from time to time, but I think it would work out well. Good luck!

    I am so pleased to have come across this recipe. I really love using things from scratch, so great that I will now be able to make my own sweetened condensed milk 🙂

    I love making foods like this. I know I can get it at the store but why not make it, especially if it keeps for a while. Plus, the cost of sweetened condensed milk is pricey.

  6. Baking soda would only help if you are taking it all the way to dulce de leche. The basic properties speed up the Mailard reaction that caramelizes proteins. Try adding some to onions while you caramelize them.

    1. That’s so interesting! Thanks for sharing Amber, I have definite plans to make some dulce de leche, so I will give that a try, and awesome tip for the onions!
